claims. (c1. 113-99) This invention relates to new and useful improvements in type gages and soldering jigs, particularly adapted for correctly determining the positiontof type to be set in a typewriting machine and for holding the type blocks in place while they are soldered to the type bars.

.When replacing worn type blocks or changing the characters of the type blocks o-f la typewriting machine or the like, it is important that the type blocks berigidly so positioned on the type bars as to print in proper alignment and effect a full Auniform impression. Therefore, the type block must be set on the type bar at an exact distance or radius from the pivot upon which the bar swings, and the block must also be set on the bar as such an angle as to cause the type to strike flatly against therplaten. Methods and devices heretofore employed for this purpose have through one of the platen shaft journal openings of the typewriter carriage, whereby the type is ltted to the particular machine being serviced.

not only been unwieldly and involv-ed manipula- Thus, a service instituV purchase and keep at hand a large variety of devices to permit servicingy the several makes, styles, sizes and types of machines. Furthermore, the devices heretofore used have frequently been bulkyrand cumbersome and required a substantial disassembly ofthe typing. machine to effect replacement or ,installation of new type blocks thereon. Y It is, therefore, one object of this invention to provide an improved type gage and soldering jig for definitely and positively positioning the type block in proper printing position with respect to the platen, said" device being arranged to hold the type block in such correct position during the operation of soldering the block to the type bar.

` An important object of the invention is `to provide a type gage and soldering jig, of the character described, which is adapted foruse with various types and sizes of typewriting machines and which is provided with means for positively adjusting and locating'the type block table or platform for correctly positioning and holding the type blocks whilethesame are soldered to the type bars; such gage also being adapted for use in holding and positioning the type of machines in which the type bars are adjustably lAnother object of the invention is to provide in a device of the character described means for positively and resiliently holding the type bar in place in the notch or slot at the back of the type block while vthe block is soldered to the bar.

Still vanother object of the invention is to provide in a type gage and soldering jig of the character described -a type positioning lug on the type platform or table, which lug may be adjusted in position longitudinally and radially of the axis of the platen shaft and tangentially of the platen surfaceywhereby the type may be positively accurately aligned and positioned for correctstriking on the platen.

A still further object of the invention is to provide in a type gage and soldering jig of the character described a movable table or type platform having means for positively adjusting it in position and means for locking the platform or table inthe proper adjusted position.

Still another object of the invention is to provdein a type gage and soldering jig ofthe character described means providing for positively setting the-table or type platform at the correct platen diameter.

mounted on their pivot shaft, whereby the type f vStill another o-bject of the invention is to provide a type'gage and soldering jigV of the character described which is small and easily installed and used and which does not require cornplete or substantial dismantling of the typewriter to permit replacement of used type or inl stallation ofnew type blocks 'tl'iereonv wherein: Y

Figure 1 is a top plan view 'of'a type gage an soldering jig embodying the invention, v

Figurev 2 is a longitudinal vertical sectional view of the device of Figure l, l l l Figure 3is a longitudinal vertical sectional view taken atright angles to the View of Figure 2,

Figure 4 is a fragmentary view, in elevation,` of the back of the device of Figure 1, illustrating the means by which the type table or platform may be positioned` at correct platen diameter,` and to move longitudinally inwardly' and outwardly l therein. The sleeve is provided with oppOsed key slots I3, and a restraining screw I4, having its inner end projecting into one of the key slots I3, is threaded through the wall of the body` I for retaining the sleeve in the bore of the 'body and guiding its longitudinal movement therein. A' thumb screw I5 is threaded through the wall of `thebodyopposit the retaining screw I4 and has a tip adaptedV to engage in the other key slot I3 for locking the sleeve against longitudinal and rotative movement in the bore of the' body. By loosening the thumb screw I5 the sleeve may be adjusted' longitudinally inwardly and outwardly of the bore of the body and then'locked ina desired adjusted position by ltightening said thumb screw.'

An arbor member I6 is rotatably mounted in the bore of the sleeve I2 and extends therethrough into a reduced portion Il of the bore of the body. The outer end portion of the arbor is enlarged in diameter and fits in an enlargementin'the bore of the sleeve I2, whereby the arbor is limited in its inward movement into the sleeve.A An external annular groove I8 is formedin the periphery of the enlarged portion of the arbor and a retaining screw I9 is threaded through the wallof an enlarged flange portion 20 onthe outer end of the sleeve and has its tip engaging in the annular groove I8 to retain the arbor in position in the sleeve. A set screw 2I is also threaded through the wall of the flange portion of the sleeve and likewise engages in the annular groove E8 of the arbor member, whereby the screw may be tightened tcflock the arbor member against rotation about its axis in the Y An elongate cylindrical clamping shaft or screw 22 has one endsecured by set' screws 23 in an axial opening formed in the outer end of the arbor IE and'projects axially outwardly beyond the'outer end of said arbor. The outer end of the arbor is provided with an enlarged axial bore 26.1, and a centering member 25'surrounds the clamping shaft 22. and is'slidable longitudinally on said shaft in the bore 24 of the arbor. A spring 26. is confined between the innerend of the centering member and the inner end of Ythe bore 24 in the arbor and acts to urge the center ing member outwardly from within such bore. An elongate annular groove 2Iis former in the cylindrical surface of the centering member, andv a retaining screw 28i threaded through the wall ofv the outer end of the arbor engages in suchl groove and prevents displacement of the center'- ing member outwardly from within the bore Aof the arbor. Due toY the length of the groove 2l,

however, the centering member mayv undergo a limited longitudinal movement in the bore24.

The outer end of the centering member is substantially conicalin shape, whereby the shaft 22 may be centered in the platen shaft bearing opening O of the carriage frame C of a typewriting machine. The shaft extends completely through said opening and a clamping nut 29 is threaded onto its outer 'end for vdrawing the end of theV arbor I6 against the carriage frame upright C, whereby the body II) and its associated parts are rigidly and securely held in position on the carriage with their axis extending along the line of theaxes of the platen shaft bearing openings oi the typewriting machine. 1f desired, ay washer 3`may be interposed between the clamping nut and the carriage C of the typewriter to reduce friction as the clamping nut is tightened.

" A type supporting table or platform 35, preferably. substantially rectangular in configuration,

has a depending shank 36 located substantially centrally of its underside, and said shank extends through a diametrical opening 31 formed in the body I0. The shank has a key slot 3B formed longitudinally thereof, and an elongate locking screw 39 is screw-threaded axially into the end of the body IO'and extends into the diametrical opening 31. rThe end of the locking screw 39 engages in the key slot 38 for guiding the type supporting table or platform in its radial movement with respect to the body Ill, and said locking screw is adapted to be tightened to secure the platform atl any desired adjusted position.

The portion of the body I0 underlying the platform 35 is cut away to provide a recess 4I) into which the platform may be moved tov bring the upper surface of saidplatform into tangential alignment with the outer periphery of the cylindrical portion of the body. AThis provides rfor adjustment of the platform to a minimum platen diameter, but permits the platform to be moved radially outwardly of the axis kof thev body to a position which would be tangential to platens of larger diameters. A

An adjustable type-supporting plate is slidable longitudinally in aV groove 46'formed in the upper surface of the platform v35, Onen upper longitudinal edge of the plate 'isfcut away and engages under an inwardlyprojecting flange 41 carried by said platform, whereby the plate is retained and guided in its longitudinal movement in said groove.y The plate 4,5., is providedwith a laterally extending bifurcated arm 48 located substantially centrally of said plate, andthis arm extends into a large recessf 49 formed inthe table or platform 35, as clearlyshown in Figure 5. The bifurcated sections of the arm engage on either side of a square nut 50 whichis threaded onto an elongate adjusting screw `5I extending through said recess parallel to the vmovable'supporting plate. 4 Obviously, theV adjusting screw may be threaded directly through the armfif desired, in which case thel squarenut couldY be omitted. The adjusting screwy is provided with an external annular retaining flange 52 spaced inwardly from the head 53 of said screw and adapted to engage against the upper wall', of the recess in said platform to pre/vent longitudinal movement of theV adjustingl screw. Rotationfoi the adjusting screw will cause .movement ofy the square nut 5I) longitudinally of said adjusting screw and, due to the engagement, of the bifurcated arm 48 with said nut, will cause corresponding'movement of the supporting plate.

The outer ends of the bifurcated sections of the arm 4 8 extend beyond the ySquare nut 5I! and are engaged by a pressure plate 54 having a wedge mock 55 formed thereon. A Wedge mantel` 56', having a taper corresponding to the taper of the wedge block 55, is threaded ontdan elongate locking screw 5l, whereby the wedge'SB-m'ay be moved longitudinally of said 'lockingscrewNr The surface of the wedge 56 opposite the wedge block 55 is adapted to slide along the outer vertical side wall of the recess d9, so that when the wedge is moved longitudinally on the locking screw in one direction the tapered surfaces of the wedge and wedge block will cause the plate 54 to be pressed irmly against the ends of the bifurcated sections of the arm 48 and thus frictionally hold the supporting plate 45 in any desired adjusted position. The locking screw is provided with an external annular flange 58 spaced from its head 59 and adapted to engage against the upper wall of the recess to prevent longitudinal movement of said locking screw.

It will be seen, therefore, that the locking screw l may be rotated to withdraw the wedge 55 from wedging engagement with the wedge block 55, whereupon the adjusting screw 5| may be rotated to cause movement of the square nut 55 longitudinally thereon and thus cause corresponding longitudinal adjustment of the supporting plate 45. When the sup-porting plate has been moved to the desired position, the locking screw 5l may be rotated to force the wedge 56 between the wall of the recess and the wedge block 55 to press the plate 54 against the ends of the sections of the bifurcated arm 48 to lock the supporting plate in such adjusted position.

A thin at cover plate 50 is secured by screws 5l to the upper surfaceof the platform for covering the recess 49 and the mechanism contained therein. The inner edge of the cover plate also overlies the edge of the supporting plate 45 opposite the iiange ll and, with said flange, lconfines the supporting plate a-gainst displacement from the groove 45.

An upstanding positioning lug 65 is provided on the upper surface of the supporting plate 45 and is elongated transversely of said supporting plate. This lug is adapted to engage against one end of the characters (not shown) of a type block T for rcorrectlypositioning the type block in a manner which will be hereafter more fully explained. If desired, an insert of asbestos or similar heat resisting material 56 maybe mounted in a recess on the upper surface of the supporting plate for limiting dissipation of heat from the type block as the same is soldered to the type bar B. The asbestos insert may, however, be omitted since it is not essential to the'invention. v

A type block ,clanfuoin-g member 61 is adjustab-ly secured to the cover plate 69 by meansof screws 59and has a pair of spaced contacting lingers 59 provided thereon for engaging against the side of the type block. The fingers 59 are spaced from the upper surface of theplatform 35, whereby they engage the side of the type block at a point above the face thereof. A latch member 'i9 is pivotallymounted on the upper surface of the platform on the opposite side of the movable supporting plate @5 from the clamping ngers 59 and is disposed substantially centrally between the spaced fingers, as clearly shown in Figure l, whereby the type block is rigidly gripped between the ngers of the clamping member and the tip of the latch member.

Furthermore, the supporting plate may be magnetized if desired, in which event the magnetic rotatably mounted in a vertical opening I3 formed in the type supporting platform. An elongate fiat spring member M is mounted in an elongate recess l5 formed in the underside of the platform and one arm of the spring member engages in a notch le formed in the lowel1 portion of the pivot pin l2, whereby when the pin is turned the spring urges the pin to return to the position shown in Figures 1 and 3, whereby the latch member l5 is then normally urged to and held in tight block engaging position. The latch member is preferably provided with an elongate handle section 'il which is bent downwardly and backwardlyupon itself, as shown in Figure 3. The backwardly turned portion of the arm is adapted to engage the upper surface of the platform when the latch member is swung to disengaged position, whereby the latch member will be irictionally retained in such disengaged position. If desired, however, the underturned por-` ti-on of the handle may be omitted.

Aportion of the periphery of the body l@ is cut away to provide a planar surface Se lying in a plane extending radiallg7 inwardly through the axis of said body and parallel to the upper surface of the type supporting platform 35 and the supporting plate i5. Measurements may thus be taken between the planar surface 8!! and the upper surface of the type supporting plate l5 to set the platform 35 so that the supporting plate i5 will lie in a plane which would be tangential to the platen of the machine being serviced. The distanceloetween the planar surface S9 and the surface oi" the supporting plate i5 is thus set to be equal to the radius of the platen of the machine being serviced, whereby the surface of the force will initially hold the type block in ilat con- Y tacting position on the surface of said plate. The

type block so initially held in place by such magsupporting plate l5 will be positioned properly to receive the type block B in the same manner as if the type block were engaging the platen of the machine.

For resiliently and positively maintaining the type bar B, shown in dotted lines in Figure 3, in correct position in the notch or slot provided in the back of the type block T, whereby the bar may be soldered in place in such notch or slot, a pressure head is provided. The pressure head is carried on the lower end of an elongate pin 8S having a finger grip 8l! at its upper end and extending Vdiametrically through one end of an adjusting sleeve 89. A spring interposed between the pressure head 85 and the outer end of the sleeve 88 and surrounding the shaft 86 normally urges the pressure head downwardly into engaging position. The adjusting sleeve slidably telescopes one arm of an L-shaped supporting rod or bar 89 and is held in adjusted positions thereon by a set screw 9i) threaded through the wall of the inner end of said sleeve and engaging said arm.

The other arm of the L-shaped supporting bar is slidably mounted in an upstanding socket member 9| which has its lower end portion secured in an opening in the enlarged flange portion 2G of the sleeve I5 by means of a retaining screw 92. The inner end of the retaining screw engages in an annulargroove 93 formed in the reduced portion of the socket member, whereby vsaid socket member may berotated about its axis. A set screw 94 is screw-threaded throughA the wall of the socket member near its upper end for engaging and locking the supporting bar 89 at various adjusted elevated positions with respect to the socket member.

Manifestly, the socket member SI may be roscrew to the headr of a pivot pin l2kwhich is H tatedabout its axis to vswing the sleeve 88 and 7 the pressure head carried thereby toward and from the type block supporting platform 35, whereby the pressure head may be moved to engage the type bar to hold the same in place in the notch or slot in the back of the type block and may be removed from such holding position.

In using the type gage and soldering jig, the platen and platen shaft of the typewriting machine are first removed from the carriage C. The distance between the planar surface 80 and the upper surface of the supporting plate 45 is set equal to the radius of the platen of the machine by loosening the locking screw 39 and moving the platform radially to the correct position and tightening the locking screw. The elongate clamping shaft 22 is then inserted through the platen shaft bearing opening O in the carriage frame, and the clamping nut 29 is tightened to draw the outer end of the arbor I6 into engagement with the carriage frame. The conical end of the centering member 25 enters the opening O and, as it is pressed back against the force of the spring 25, guides and centers the shaft and arbor, whereby the body lil and the associated parts are positively and rigidly supported in axial alignment with the centers of the platen shaft bearing openings.

If the diameter of the bearing opening O is considerably larger than the diameter of the shaft 22 or if the opening is slotted instead of circular, a bushing or sleeve 91, having an external diameter fitting the bearing opening O` and having an internal diameter closely fitting the shaft 22, may be mounted on the shaft between the end of the arbor and the inner end of the clamping nut. This will assure correct centering and axial alignment of the device in the platen shaft bearing opening.

The carriage of the typewriter is then locked against side movement in any suitable manner, as by means of the margin stops of the machine, by means of the tabularV stops, or by pressing the space bar downwardly and tying it in such de'- pressed position whereby the escapement dog limits movement of the carriage, or in lany other suitable manner. The thumb screw i5 is then loosenedto permit the body lil to be moved longitudinally with respect to the sleeve I2, whereby the type supporting'pla'te [.5 may be centered at the striking point of the typepar and type blocks".

With such longitudinal adjustment effected, the thumb screw i5 is tightened to lock the body against further longitudinal movement. The thumb screw 2i in the sleeve l2 is next loosened and the body lil is turned about its axis until the upper surface of the type supporting plate is in such a position that the face of the type lies flat against the surface of the supporting plate', whereupon the thumb screw 2| is tightened to lock the body against further rotation. In normal practice, the type supporting platform 35 has already been moved radially outwardly with respect to the axis of the body Ill until the surface of the supporting plate (t5 is spaced from thecenter of the body by a distance equal to the radius of the platen of the machine being serviced. Thus, the surface of thefsupporting plate d5 is so positioned that it would be tangential to the platen of the typewriter, whereby it stops the type at the same point at which such type would strike the platen in use.

Next, the type key is depressed to cause the type bar to swing the type block to printing position, Where the face of the type block engages squarely against the upper surface of the supporting plate 45. The locking screw 51 is then rotated to move the wedge 56 away from the wedge block 55, whereby the adjusting screw 5l may be turned to move the supporting plate 45. The supporting plate is moved until the upstanding lug 65 engages against either the upper or lower end of the character on the face of the type block. With the supporting plate so adjusted, the locking screw 5'! is again rotated to move the wedge 56 toward the wedge block 55 to move the pressure plate 5d into tight frictional anchoring engagement with the ends of the sections of the bifurcated arm G8, whereby the supporting plate is securely held in such adjusted position.

rIhe ends of the fingers 69 of the clamping members 6l should now engage one side of the type block, but if they do not the thumb screw I5 may be loosened and the body l0 adjusted until the tips of the fingers do lightly engage the side of the block. The latch member 'lil can then be moved to the engaging position shown in Figure 3 to securely clamp the type block between the latch member and the fingers B9 and in tight engagement with the upper surface of the supporting plate E5.

The old type block may then be removed from the type bar by melting the solder connecting the same together. A new type block is then placed in position on the supporting plate d5 with the corresponding end of the character on the face of the block in engagement with the lug 65 and the latch 'Eil is moved to clamping position to hold the block in such position. The type bar mayr then be swung into the notch or slot in the back of the block and the pressure head swung over the type bar, as shown in Figure 3, to positively and resiliently hold said bar in position in such slot or notch. Solder may then be run into the notch to secure the bar to the type block.

After the solder has cooled and hardened suiliciently, the pressure head 55 may be swung from its holding position to permit the type bar to swing back away from printing position, and another bar and block swung into place on the supporting plate whereupon the process just described may be repeated to replace the type block.

Where the type characters have upwardly or downwardly extending portions, such as have the letters h and p, the lug 6,5 may be moved to contact the portion of the character not so extending above or below the line of the main portion of the character, whereby the type block may be correctly secured to the type bar to maintain the character in proper alignment with the other characters. Thus, by comparison with properly aligned characters, an entire set of type blocks may be properly secured to the type bars of the typewriting machine.

Obviously, since the type blocks are all aligned by means of the ends of the characters on the face thereof engaging the upstanding lug 65, the type impressions will all be in proper alignment. Furthermore, since the surface of the supporting plate 45 was adjusted into correct tangential striking position, the type characters will strike the platen flatly to obtain a full, even impression.

To assure vertical alignment of the type block, the clamping member 51 may be adjusted to bring the tips of the ngers 59 into vertical alignment. This may be done by loosening one of the screws 68 and pivoting the clamping member about the other screw until the correct position has been obtained, whereupon the rst screw mounted on their pivot shaft may be adjusted to align the type characters by using the type gage and soldering jig as a gage to position the type characters properly and then adjusting the connection of the type bars on the pivot shaft.

From the foregoing, it will be seen that an l improved type gage and soldering jig has been provided which is adapted for usewith type- Writingmachines of various makes, rvstyles, sizes and types, for aligning and correctly positioning the type characters on the face of type blocks. It will particularly be noted that the' type gage and soldering jig is adapted to be rigidly clamped and supported lon the typewriting machine car-.- riage in the correct position for aligning and positioning the type characters, whereby the ltype is fitted to the particular `machine being lserviced and is assured of being properlyaligned and positioned for full Vprinting impression. It will further be seen that means has been provided on the type gage and soldering jig for positively and resiliently holding the type bars in place in the notch or slot at the back of the type blocks while the blocks are being soldered to such bars, and that holding means is provided on the table or platform forrpositively adjusting and holding the type block in correct position for such soldering. Also, themovable table or type platform has means forpositively adjusting the type supporting plate thereon in position for properly aligning thetype characters and means is provided for positively settingand holding the supporting plate in such correct type aligning position. Furthermore, means has been provided for accurately setting lthe type supporting surface of the platform at correct platen diameter. It will particularly be noted that a type gage and soldering jig has been provided which is small and easily installed and used, and which does not require any substantial dismantling Vof the ytypewriting machineto permit replacement of used type or installation ofV new type blocks on 'the' type bars of such machine. i

It is particularly important to note that, since the type gage and solderingjig is secured to only one side of the carriage frameof the ma-4 chine being serviced, it is readily interchangeable and usuable in machines having different carriage widths, as Well as on different makes and types of machines. The sleeve or bushing 91 also permits thedevice to be used on various machines having platen shaft bearing openings larger than the centering member oron machines having Vslotted platen shaft openings rather than circular openings.

The foregoing description of theinvention-is. explanatory only, and changes in the details of the construction illlustrated may be made by those skilled'in the art, within the scope of the appended claims, without departing from the spirit of the invention. K
